Description

Technical Field

[0001] This application relates to the technical field of unmanned vessels, and in particular to a retractable catamaran. Background Technology

[0002] Unmanned ships have evolved from traditional navigation tools into modern high-performance vessels, with equipment configurations expanding from basic power to diversified scientific research and living facilities. With technological innovation, the potential of unmanned ships in the fields of marine economy, military and tourism will continue to be released.

[0003] Currently, the marine hydrological multi-parameter profile observation system based on unmanned surface vessels (USVs) with publication number CN119079027A includes a USV, a control system installed on the USV, and a data acquisition system. The data acquisition system includes a hydrological acquisition subsystem, a meteorological acquisition subsystem, a spatiotemporal information acquisition subsystem, and a profile observation device subsystem. The hydrological acquisition subsystem includes a CTD multi-parameter sensor installed on an electric winch device and an ADCP sensor installed under the hull of the USV.

[0004] Regarding the aforementioned technologies, since the ADCP sensor is located under the hull of the unmanned surface vessel, it is immersed in water for a long time. The ADCP sensor is prone to electrochemical corrosion due to prolonged contact with water (especially seawater), which leads to a decrease in the strength of the shell, bracket, or screws, or even perforation, resulting in a reduction in the service life of the ADCP sensor. Therefore, underwater equipment mounted under the hull of the unmanned surface vessel is prone to a reduced service life due to prolonged immersion in water. Utility Model Content

[0005] To improve the service life of underwater equipment, this application provides a catamaran that is easy to deploy and retract.

[0006] This application provides a technical solution for an easily deployable and retractable catamaran:

[0007] A retractable catamaran includes:

[0008] The ship has two hulls, and a control console is provided between the two hulls. A connecting frame is provided between the control console and the hull, and the connecting frame fixes the control console between the two hulls. The bottom of the control console has a mounting groove.

[0009] The retractable assembly includes a rotating frame and a driving component. The rotating frame is rotatably connected to the inner wall of the mounting slot. One end of the driving component is mounted on the rotating frame, and the other end is mounted on the inner wall of the mounting slot. The driving component is used to drive the rotating frame to rotate.

[0010] The mounting base is installed at the end of the rotating frame away from the inner wall of the mounting groove, and the mounting base is used to install underwater equipment.

[0011] By adopting the above technical solution, the rotating frame is driven to rotate downwards during use, so that the mounting base on the rotating frame is submerged in water, allowing the underwater equipment on the mounting base to work underwater.

[0012] Once the work is completed, the hull is moved to the water's edge, and then the drive mechanism is used to drive the rotating frame upward, causing the mounting base to detach from the water surface, thus allowing the mounting base to carry the underwater equipment out of the water at the same time.

[0013] When the catamaran is docked at the shore, the underwater equipment can be taken out of the water, thus keeping the underwater equipment dry and facilitating maintenance of the underwater equipment while the catamaran is docked at the shore.

[0014] Optionally, the rotating frame includes a rotating shaft, support rods, and connecting rods. Multiple rotating seats are installed at the bottom of the mounting groove. Multiple rotating ears are fixedly connected to the rotating shaft. Each rotating ear is hinged to a rotating seat. Multiple support rods are provided. Each support rod is fixedly connected to the rotating shaft, and each support rod is fixedly connected to the connecting rod. The mounting seat is fixedly connected to the end of the connecting rod away from the rotating shaft.

[0015] By adopting the above technical solution, multiple rotating ears on the rotating shaft are used to hinge multiple rotating seats at the bottom of the mounting slot, making the connection between the rotating shaft and the control console more stable. At the same time, multiple support rods are used to fix the connecting rod, making the connecting rod more stable, thereby increasing the load installed on the connecting rod.

[0016] Optionally, the rotating frame further includes a reinforcing rod, and a plurality of the support rods are fixedly connected to the reinforcing rod, with one end of the driving member hinged to the reinforcing rod.

[0017] By adopting the above technical solution, the reinforcement rod increases the structural strength of the support rod, prevents deformation, and ensures stable driving of the drive component to the support rod and connecting rod.

[0018] Optionally, the driving component includes a driving seat, a telescopic rod, and a connecting seat. The driving seat is fixedly connected to the bottom of the mounting groove. One end of the telescopic rod is hinged to the driving seat, and the other end is hinged to the connecting seat. The connecting seat is fixedly connected to the reinforcing rod.

[0019] By adopting the above technical solution, and utilizing the cooperation of the drive seat, telescopic rod, and connecting seat, the reinforcing rod is driven to rotate around the rotation axis by controlling the extension and retraction of the telescopic rod.

[0020] Optionally, the distance between the mounting base and the rotation axis is greater than the distance between the edge of the console and the rotation axis.

[0021] By adopting the above technical solution, when the mounting base is rotated to the water surface, it is located outside the mounting groove, which facilitates the maintenance, repair and replacement of underwater equipment on the mounting base by the staff.

[0022] Optionally, the control panel has a locking hole, and the mounting base is fixedly connected to a locking protrusion. When the connecting rod is rotated to a state parallel to the control panel, the axis of the locking protrusion coincides with the axis of the locking hole.

[0023] By adopting the above technical solution, and utilizing the cooperation of the locking hole and the locking protrusion, when the locking protrusion and the locking hole are coaxial, the locking device can be used to lock the locking protrusion through the locking hole, thereby locking the mounting base, preventing the mounting base from shaking, enhancing the stability of the mounting base, and reducing the load on the driving component.

[0024] Optionally, the console is equipped with multiple cameras, and the multiple cameras are all facing different directions.

[0025] By adopting the above technical solution, the installation of multiple cameras provides all-round monitoring of the catamaran, thereby improving the safety of the catamaran during operation.

[0026] Optionally, the console may be equipped with multiple searchlights.

[0027] By adopting the above technical solution, the setting of multiple searchlights can easily adapt to the lighting needs of the camera in different environments.

[0028] Optionally, a lidar is installed on the control console, and the lidar is oriented along the length of the hull.

[0029] By adopting the above technical solutions, using lidar for ranging and obstacle detection, the accuracy and safety of catamaran navigation can be improved.

[0030] Optionally, the control panel is equipped with two lamps, one of which is close to one side of the hull and the other is close to the other side of the hull, and the two lamps have different lights.

[0031] By adopting the above technical solution, two different colored lights can be used to make it easier to identify the direction of movement of the catamaran at night, and the lights can also enhance the nighttime warning effect.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] By coordinating the hull, control console, connecting frame, mounting slot, rotating frame, drive components, and mounting base, the underwater equipment can be removed from the water when the catamaran is docked at the shore, thus keeping the underwater equipment dry and facilitating maintenance of the underwater equipment while the catamaran is docked at the shore.

[0034] By cooperating with multiple rotating seats, rotating shafts, multiple rotating ears, multiple support rods, and connecting rods, the connection between the rotating shaft and the control console becomes more stable, thereby increasing the load capacity on the connecting rods.

[0035] By coordinating the drive seat, telescopic rod, and connecting seat, the extension and retraction of the telescopic rod is controlled to drive the reinforcing rod to rotate around the rotation axis. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0042] This application discloses a retractable catamaran.

[0043] Reference Figure 1 and Figure 2A retractable catamaran includes two hulls 1, with a control console 2 positioned between them. A connecting frame 3 secures the control console 2 to the hulls 1. A mounting groove 21 is formed at the bottom of the control console 2. A retraction assembly 4 is housed within the mounting groove 21. The retraction assembly 4 includes a rotating frame 41 and a drive component 42. The rotating frame 41 is rotatably connected to the inner wall of the mounting groove 21. One end of the drive component 42 is mounted on the rotating frame 41, and the other end is mounted on the inner wall of the mounting groove 21. The drive component 42 drives the rotating frame 41 to rotate. A mounting base 5 is mounted on the end of the rotating frame 41 furthest from the inner wall of the mounting groove 21. The mounting base 5 is used to mount underwater equipment. By utilizing the cooperation of the drive component 42 and the rotating frame 41, the underwater equipment mounted on the mounting base 5 is transferred to the water surface, reducing damage caused by prolonged immersion in water and thus extending the service life of the underwater equipment.

[0044] In this embodiment, the control console 2 is square, and multiple cameras 11 are installed on the square control console 2. In this embodiment, there are four cameras 11, and the four cameras 11 are respectively installed on the four sides of the square control console 2. The four cameras 11 are used to monitor the control console 2 from all four directions, thereby improving the safety of the catamaran during operation.

[0045] In an optional embodiment, a plurality of searchlights 12 are installed on the control console 2. In this embodiment, there are two searchlights 12, and the two searchlights 12 face the bow of the ship 1. The arrangement of the searchlights 12 is convenient to adapt to the lighting needs of the camera 11 in different environments.

[0046] A lidar 13 is installed on the control console 2 near the bow of the hull 1, with the lidar 13 facing the bow of the hull 1. The lidar 13 is used for ranging and obstacle detection, thereby improving the accuracy and safety of catamaran navigation.

[0047] Two lights 14 are installed on the control console 2. One light 14 is closer to one side of the hull 1, and the other light 14 is closer to the other side of the hull 1. The two lights 14 have different colors; in this embodiment, one light 14 is red and the other is green. Using two lights 14 of different colors makes it easier to identify the direction of movement of the catamaran at night, and the arrangement of the lights 14 also enhances the nighttime warning effect.

[0048] Reference Figure 2 and Figure 3The rotating frame 41 includes a rotating shaft 411, a support rod 412, and a connecting rod 413. Multiple rotating seats 22 are mounted on the bottom of the mounting groove 21. Multiple rotating ears are fixedly connected to the rotating shaft 411. In this embodiment, two rotating seats 22 are provided at the bottom of the mounting groove 21. In other embodiments, three or four rotating seats may be provided at the bottom of the mounting groove 21 depending on the length of the rotating shaft 411. In this embodiment, two rotating ears are also provided on the rotating shaft 411, each hinged to a corresponding rotating seat 22. The hinged connection between the two rotating ears on the rotating shaft 411 and the two rotating seats 22 at the bottom of the mounting groove 21 makes the connection between the rotating shaft 411 and the control console 2 more stable.

[0049] Multiple support rods 412 are provided. In this embodiment, two support rods 412 are provided, but in other embodiments, four or six support rods may also be provided. Both support rods 412 are fixedly connected to the rotating shaft 411, and both support rods 412 are fixedly connected to the connecting rod 413. The two support rods 412 are symmetrically arranged about the connecting rod 413. The mounting base 5 is fixedly connected to the end of the connecting rod 413 away from the rotating shaft 411. The fixed connection between the two support rods 412 and the connecting rod 413 makes the connecting rod 413 more stable, thereby increasing the load that can be installed on the connecting rod 413.

[0050] The rotating frame 41 also includes a reinforcing rod 414, and two support rods 412 are fixedly connected to the reinforcing rod 414. One end of the driving component 42 is hinged to the reinforcing rod 414. The reinforcing rod 414 increases the structural strength of the support rods 412, prevents deformation, and ensures that the driving component 42 stably drives the support rods 412 and the connecting rods 413.

[0051] The driving component 42 includes a driving base 421, a telescopic rod 422, and a connecting base 423. The driving base 421 is fixedly connected to the bottom of the mounting groove 21. One end of the telescopic rod 422 is hinged to the driving base 421, and the other end is hinged to the connecting base 423. The connecting base 423 is fixedly connected to the reinforcing rod 414. In this embodiment, the telescopic rod 422 is an electric push rod. By utilizing the cooperation of the driving base 421, the telescopic rod 422, and the connecting base 423, the extension and retraction of the telescopic rod 422 drives the reinforcing rod 414 to rotate around the rotation axis 411.

[0052] The distance between the mounting base 5 and the rotating shaft 411 is greater than the distance between the edge of the control console 2 and the rotating shaft 411. This ensures that when the mounting base 5 is rotated above the water surface, it is located outside the mounting groove 21, making it easier for personnel to maintain, repair, and replace the underwater equipment on the mounting base 5.

[0053] The control console 2 has a locking hole 23, and a locking protrusion 6 is fixedly connected to the mounting base 5. When the connecting rod 413 rotates to a state parallel to the control console 2, the axis of the locking protrusion 6 coincides with the axis of the locking hole 23. When the locking protrusion 6 and the locking hole 23 are coaxial, a cylindrical locking device can be passed through the locking hole 23 and fitted onto the locking protrusion 6 for locking. By utilizing the cooperation between the locking hole 23 and the locking protrusion 6, the mounting base 5 is locked, preventing the mounting base 5 from shaking, enhancing the stability of the mounting base 5, and reducing the load on the drive component 42.

[0054] In this embodiment, the underwater device on the mounting base 5 is an underwater robot. In other embodiments, other underwater devices, such as ADCP sensors, water quality monitoring devices, etc., can also be installed.

[0055] The implementation principle of a retractable catamaran according to an embodiment of this application is as follows: During the use of the catamaran, the telescopic rod 422 is extended. The extension of the telescopic rod 422 drives the support rod 412 and the connecting rod 413 to rotate downward around the rotating shaft 411 through the reinforcing rod 414, so that the mounting seat 5 on the connecting rod 413 is submerged in the water, thereby enabling the underwater equipment on the mounting seat 5 to work underwater.

[0056] Once the work is completed, the hull 1 is moved to the water's edge, and the telescopic rod 422 is shortened. The telescopic rod 422 is extended and, through the reinforcing rod 414, synchronously drives the support rod 412 and the connecting rod 413 to rotate upward around the rotating shaft 411, causing the mounting base 5 to leave the water surface, thereby allowing the mounting base 5 to carry the underwater equipment and leave the water surface at the same time.

[0057] When the catamaran is docked at the shore, the underwater equipment can be taken out of the water, thus keeping the underwater equipment dry and facilitating maintenance of the underwater equipment while the catamaran is docked at the shore.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
